[quote]]Do you randompy get engrams or how do they drop?[/quote] Well. U dont get the randomly. However there are a few ways to earn them. As rewards after crucible or a strike, im assuming after raids, end of story missions we can get them. Leveling up crpytarch we can get them. And good old fashion just killing enemies can drop them. Chests can have them. Im sure i missed a few. Point is they are plentiful. [quote]Second question: skill/level upgrade: a mix of just using it like the jumping and doing damage like nova bomb and grenades, damage equals exp? What is the system behind the upgrades?[/quote] So. U have an exp bar. As u kill enemies, accomplish tasks. U will gain experience. This goes into your bar. Everytime u fill the exp bar. U get a skill point for te subclass u are working on at the moment. After level 20. U still get the point. But u also generate an orb of light. For more in depth info post level 20.
